UPDATE: A nine-year-old girl who had been missing since yesterday has been found "safe and well".
Police had launched a land search in an attempt to find Wendy Hazel Muranda, who had not been seen since 3pm on Friday at her house on Radiata Way, Ellenbrook.
At 9.30am today, police announced Wendy had been found safe and well at an "associate's" house in Ellenbrook.
A police spokesman said the associate was a boy who was a couple of years older than Wendy.
He said officers would investigate the incident, but at this stage there were no indications anything “untoward” had happened at the boy's house.
Wendy apologised and promised not to run away again as she left Ellenbrook police station with her mother Blessing Muranda this morning.
Earlier in the day, Ms Muranda told reporters her daughter had run away after fighting with her sister.
She said Wendy often visited parks but always came home at night.
Family and friends had been conducting doorknocks in the area throughout the morning.
Wendy’s friend Sara Jansen said the nine-year-old trusted everyone in the community.
“She talks to everyone in our neighbourhood and she often goes off with people,” Sara said.
State Emergency Service volunteers had helped police with the search.
"Wendy may suffer from a medical condition and there are welfare concerns for her," a police spokeswoman said this morning.
